identifying watch

Hi,
not sure if this is the right forum.
I inherited an IWC watch and try to identify it's model.
There are no markings on the back except for a serial number.
the face is white, date on the right. No numerals just lines and dots inbetween.
Case color silver.
Any idea how to identify the model?

An image would be a good start,

at the moment we don't know if it is a small ladies wrist watch or a man's wrist watch.

If you can get a watch maker to remove the back, record any markings on the innner case back and the movement. It's year of manufacture and type of movement and possibly other details can be determined using
